SITUATION 4: Water is drained from a large reservoir using two horizontal pipes connected in series. The first pipe is 20 m long and has a 10-cm diameter, while the second pipe is 35 m long and has a 4- cm diameter. The water level in the reservoir is 18 m above the center line of the pipe. The pipe entrance is a sharp edged, and the contraction between the two pipes is sudden. Neglecting the effect of the kinetic energy correction factor, determine the discharge rate of water from the reservoir. Assume the friction factor for all pipes is equal to 0.02 and the loss coefficient is 0.05 for a sharp edged entrance, and is 0.46 for sudden contraction. 18 m Oil tank 20 m 35 m
